CHANGELOG
=========
2.4.0 mtleblanc's contribution:
- Indirect X zero page addressing should always wrap and stay on zero page
- BRK should disable interrupts
- ADC in decimal mode should carry between nibbles based on adjusted,
not original values.
- Writes of status register to the stack should always set M and should
set B on BRK/PHP and ~B on IRQ/NMI
- Given the above, status register does not need to track M or B bits,
removed from initialization.
- Found and tested against
https://github.com/Klaus2m5/6502_65C02_functional_tests
2.3.0
- ROM can be loaded from the directory of ROMDIR environment variable.
